Tire tread



FIG. 1 is a perspective view of a tire tread showing my new tire tread design, it being understood that the tire tread pattern is repeated over the outer circumference and shoulder of the tread, the opposite side being the same as that illustrated; and,

FIG. 2 is a enlarged fragmentary front elevation view of the tire tread thereof.

The broken line disclosure of a tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
